8Kスーパーハイビジョン家庭再生機器の研究開発状況

摘要

8Kスーパーハイビジョン（以下，8K)は，高い臨場感と実物感が得られるように，視聴覚などの人間科学的な研究に基づいて設計された映像音響システムである。8Kの理想的な視聴環境は,大画面の超高精細映像用ディスプレーと，空間的に配置された24個のスピーカーから成る22.2マルチチャンネル音響（以下，22.2ch音響）システムで構成される"。%8K Super Hi-Vision (8K) is an audio-visual system designed to achieve a strong sense of realism and presence, and it is based on research in human science areas such as visual perception. The ideal viewing environment includes a large-screen, ultra-high-resolution display and a 22.2 multichannel sound with 24 loudspeakers. The keys to home viewing will be thin and lightweight sheet-type large-screen displays and the ability to reproduce 3D spatial sound with fewer loudspeakers. This report introduces the state of R&D on 8K displays and 3D sound systems suitable for home viewing. It introduces LCD displays that have been developed for ultra-high definition video as well as initiatives, based on recent research at STRL, toward implementing a practical sheet-type organic electroluminescence (EL) display. Regarding 3D sound systems, it introduces the state of R&D on a display-frame loudspeaker system for the home, which uses trans-aural playback technology to present 22.2 multichannel sound on fewer loudspeakers.
